What’s Full Disk Encryption?

Do you know what full disk encryption is all about? Don’t worry. It’s actually not as complicated as you think.

Simply put, Full Disk Encryption (FDE) encrypts the data at the hardware level. What does that mean? It means that data is uploaded onto a hard drive. Only admins are able to read that data.

If you’re not an admin, all you need is a key to decode it. Don’t try to remove the hard drive, you still won’t be able to read the data.

On the other hand, there’s a bright side to FDE. It can encrypt all data. Now, you are likely asking: “Is the process fast or slow?” Well, it all depends on how much data is being used at the same time.

Do you want that process to be faster? You can use Bitlocker. Your data will never be more secure. And, you can easily manage all that data with BitTruster. It’s fast, cost effective and really easy to manage.

With FDE and BitLocker combined, all your data can be safer than ever before.

FDE has a lot more benefits, but also some negatives. Here are some of them:

  • It encrypts a lot of data. You have to always encrypt your data. All you need to do is add software. Although, this won’t encrypt the bootstrapping
  • Not a lot of freedom. Yes, FDE is a lot more automatic than manual. You won’t have a say in what’s being encrypted. But, don’t worry. Encryption doesn’t hurt your data, it only secures it. Also, BitTruster can help manage that data. So that whole ordeal won’t bother you.
  • Destroying Data. FDE could write over some of your data, but don’t be alarmed. You can use cryptographic keys to lock the data that you don’t want erased. These keys come with FDE. Never destroy these keys. You never know what sort of accidents can happen in the future. So, why risk it?

BitLocker helps here too. No hacker will mess with the data.

Here’s another issue with FDE. It might block the operating system. So, make sure you encrypt that before it starts. You can use your encryption key for this. Just make sure you encrypt it before logging in.

Now that you know what FDE is all about, you’re all set. All that’s left to do is use all this knowledge on the real thing.
